Same here.
I do believe it would be more appreciated now then it was then however. Birthright has had a strong influence on many DMs I know, and yet none of us ever ran it. It plays on many tropes that are more popular now than they were in AD&D setting-happy TSR of the late 90's.
As stated before, this setting would be a perfect outlet for official...
- Mass combat rules
- Player domain/stronghold/guild management rules
- Extended downtime rules (like a whole season, or a full year)
- External power sources to fuel magic (almost à la M:tG)
- Regional magic
- A slow(er)-paced campaign construction
- An official setting with less available, yet powerful magic (I don't dare say "low magic" anymore)
- "Race/subrace" variants as bloodlines or regional traits (already explored with dragonmarks in Eberron; RftlW)
